Technical Field
The invention relates to an ultraviolet cut-off type three-layer co-extrusion composite film and application thereof.
Background
At present, polyolefin elastomer adhesive films (POE adhesive films) are gradually replacing ethylene-vinyl acetate copolymer adhesive films (EVA adhesive films) to become main photovoltaic packaging adhesive films due to excellent water resistance and better PID resistance. But the required lamination temperature of current POE glued membrane is higher, and the lamination time is longer, and the luminousness is less than the EVA glued membrane, and POE micelle cost is higher than the EVA micelle, has consequently improved photovoltaic module production energy consumption and cost, has reduced production efficiency and photovoltaic power generation efficiency, and the ultraviolet absorption performance of current POE glued membrane is lower moreover, and the ultraviolet ray is cut off the effect poor.

The ultraviolet ray cut type three-layer co-extruded composite film 40 according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, the ultraviolet ray cut type three-layer co-extruded composite film 40 according to an embodiment of the present invention includes an inner layer 41, an intermediate layer 42, and an outer layer 43.
Specifically, the inner layer 41 is an ethylene-vinyl acetate copolymer layer, the middle layer 42 is arranged on the outer side of the inner layer 41, the middle layer 42 is a polyolefin elastomer layer, and the polyolefin elastomer layer comprises the following components in parts by weight: 91.5% -98.6% of polyolefin elastomer colloidal particles; 0.1 to 1 percent of antioxidant; 0.5% -2% of thermal initiator; 0.5 to 2.5 percent of crosslinking monomer; 0.1 to 1 percent of silane coupling agent; 0.1 to 1 percent of light stabilizer; 0.1 to 1 percent of ultraviolet absorbent; and an outer layer 43, wherein the outer layer 43 is arranged outside the middle layer 42, and the outer layer 43 is an ethylene-vinyl acetate copolymer layer.
In other words, the ultraviolet-cut three-layer co-extrusion composite film 40 according to the embodiment of the present invention mainly comprises an inner layer 41, a middle layer 42 and an outer layer 43, and the inner layer 41, the middle layer 42 and the outer layer 43 are sequentially disposed from inside to outside, wherein the inner layer 41 and the outer layer 43 are both ethylene-vinyl acetate copolymer layers, the middle layer 42 is a polyolefin elastomer layer, and the polyolefin elastomer layer comprises the following components in parts by weight: 91.5% -98.6% of polyolefin elastomer colloidal particles; 0.1 to 1 percent of antioxidant; 0.5% -2% of thermal initiator; 0.5 to 2.5 percent of crosslinking monomer; 0.1 to 1 percent of silane coupling agent; 0.1 to 1 percent of light stabilizer; 0.1 to 1 percent of ultraviolet absorbent; and an outer layer 43, wherein the outer layer 43 is arranged outside the middle layer 42, and the outer layer 43 is an ethylene-vinyl acetate copolymer layer.
It should be noted that, since the molecular structure of the polyolefin elastomer is nonpolar, the compatibility between the thermal initiator and the crosslinking monomer is poor, the polyolefin elastomer is easy to precipitate, and the roll is easy to stick during the processing, so that the addition amount is limited, and since both sides of the polyolefin elastomer in the ultraviolet cut-off type three-layer co-extrusion composite film 40 are coated by the ethylene-vinyl acetate copolymer layer, the problems of roll sticking and the like do not exist. Therefore, the mass ratio of the thermal initiator to the crosslinking monomer in the polyolefin elastomer layer is higher than that of the thermal initiator to the crosslinking monomer in the ethylene-vinyl acetate copolymer layer, the crosslinking degree of the ultraviolet cut-off type three-layer co-extrusion composite film 40 can meet the requirement by adopting an ethylene-vinyl acetate copolymer hot pressing process in lamination, and the problems of roller sticking and the like do not exist, so that a plurality of small-molecular silane coupling agents can be added into the polyolefin elastomer, the expensive polymeric silane coupling agent does not need to be added, and the cost can be reduced.
Because the cost of the ethylene-vinyl acetate copolymer is lower than that of the polyolefin elastomer, the ultraviolet cut-off type three-layer co-extrusion composite film 40 can obtain high water resistance and PID resistance at lower cost, and compared with a polyolefin elastomer adhesive film, the prepared ultraviolet cut-off type three-layer co-extrusion composite film 40 improves the ultraviolet absorption performance and the photovoltaic power generation efficiency.
Therefore, the ultraviolet cut-off type three-layer co-extrusion composite film 40 provided by the embodiment of the invention combines the inner layer 41, the middle layer 42 and the outer layer 43, has the advantages of high ultraviolet cut-off performance, excellent water resistance and PID resistance, low lamination temperature, short lamination time and the like, and can reduce the production energy consumption and cost of a photovoltaic module and improve the production efficiency and photovoltaic power generation efficiency.

Further, the thermal initiator of the polyolefin elastomer layer is 0.2-0.5% higher than that of the ethylene-vinyl acetate copolymer layer, the crosslinking monomer of the polyolefin elastomer layer is 0.2-0.5% higher than that of the ethylene-vinyl acetate copolymer layer, and the mass ratio of the middle layer 42 to the inner layer 41 or the outer layer 43 is 10-50: 50-90.
